Template-Directed DNA Photoligation via α-5-Cyanovinyldeoxyuridine
摘要:
We describe an efficient template-directed photoligation of oligodeoxynucleotides (ODNs) using alpha-5-cyanovinyldeoxyuridine (alpha U-C). An efficient photoligation was produced by photoirradiation of an ODN containing alpha U-C at the 3 ' end with an ODN containing thymine at the 5 ' end in the presence of a template ODN. This photoligation method is a new and efficient way to synthesize branched ODNs.
Improved Syntheses of Halofuranose Derivatives with the Desired α-Configuration
摘要:
AbstractChlorination of ribofuranose or 2‐deoxyribofuranose derivatives was carried out in a 1,4‐dioxane solution of hydrogen chloride. This improved procedure allowed the syntheses of 1‐chloro‐α‐D‐ribofuranose and 1‐chloro‐2‐deoxy‐α‐D‐ribofuranose derivatives and offered ease of handling, high yield, and the stereo‐controlled α‐configuration at C‐I.

Pyridine-stretched2!-deoxyhypoxanthosine (strH) phosphoramidite was prepared in eight steps from Hoffer’s sugar (2!-deoxy-3,5-di-O-(p-toluoyl)-α-D-erythro-pentofuranosyl chloride). Improved synthesis of the Hoffer sugar was achieved without need for distillation or chromatographic separation of intermediates, or use of gaseous HCl. Conditions were optimised to provide a key nitrile intermediate for
